The specific embodiment
Below, with reference to accompanying drawing, to the manufacturing process of the manufacture method of the joint method of cylinder element of the present invention, composite cylindrical body, fiber-reinforced resin molded article and use said method and each embodiment of the formed products that obtains describes.
Below, at first each engineering of a plurality of methods be used to obtaining formed products of the present invention is summarized, next, each structure of the manufacturing process of the manufacture method of the joint method of cylinder element, composite cylindrical body, fiber-reinforced resin molded article is described.
-operation summary-
In order to obtain formed products of the present invention, carry out following operation: the surface at the stacked body of cylinder element or finishing die etc. sets multiple reinforcing fiber matrix materials, forms the fibrolaminar operation that sets; With bag material, cover described fibrage and it is sealed in to the operation on described outer peripheral face; By the inner pressure relief of the bag material after sealing, to the inside of bag material, inject the operation of liquid resin; Make the liquid resin injected be infiltrated up to described fibrage, and make its sclerosis or curing operation.
At first, in setting engineering, the reinforcing fiber matrix material is not formed to the microscler shape of cylinder shape, but form, be sheared into the plate object of appropriate size, and use multiple these plate objects.Specifically, as the reinforcing fiber that forms the reinforcing fiber matrix material, such as having exemplified glass fibre, carbon fiber, aramid fibre etc.As the reinforcing fiber matrix material, such as exemplifying the braids such as glass fabric, carbon cloth, aramid fibre cloth, nonwoven, glass chopped strand mats, stitch-bonded felt, loop bonding fiber cloth or by stacked sandwich material combined of above-mentioned substance etc.
Size as a reinforcing fiber matrix material of plate object for example has the total length with respect to the position that sets the reinforcing fiber matrix material, be equivalent to approximately 1/6 to 1/2 length, all right repeated segmentation, form with respect to total length, is equivalent to approximately 1/16～1/6 length.
Described setting in engineering, with respect to stacked body, be adapted to the reinforcing fiber matrix material local overlapped.For the object lesson of stacked body, illustrate respectively in the explanation of each method described later.
Multiple reinforcing fiber matrix materials are adapted to local overlapped method and have various ways.For example, exemplified following method: with respect to stacked body, the end of bonding reinforcing fiber matrix material one side, and make the outer surface of the end of opposite side and adjacent reinforcing fiber matrix material overlapping, thus, by multiple reinforcing fiber matrix materials overlapping overlap joint continuously.
In addition, also exist the reinforcing fiber matrix material along the width at junction surface and all methods that staggers towards each other and set.In addition, also can comprise sizes at described a plurality of reinforcing fiber matrix materials, the reinforcing fiber matrix material of above-mentioned different size was staggered and sets towards each other along the week of stacked body.
Overlapping knock-outs will and the resin diffusion part of setting again on the fibrage formed like this.
Knock-outs will is to improve the member of the release property of the resin after sclerosis, is to have by the resin with respect to injecting the plate that the material of non-cementability forms.
Resin diffusion part is the netted plate etc. that promotes the resin by injection diffusion, and the liquid resin injected (below, claim resin by injection) balancedly is infiltrated up in the reinforcing fiber matrix material.According to conditions such as the kind of reinforcing fiber matrix material, thickness, if resin by injection easily spreads, also can not use this resin pervasion component.
In addition, set the relief line that the inside that makes bag material forms decompression state, and at the first-class resin injection pipeline that sets of resin pervasion component.
Relief line is such as with Reduced pressure source such as vavuum pumps, being connected.Relief line can be used such as the multiholed catheter of section hollow or long ribbon shape member circumvolution curl be formed to conduit of tubulose etc.Near fibrolaminar, use adhesives or band etc. that relief line is fixed on to assigned position.
Filling line is to connect from the resin storagetank to supply with the connecting pipe of resin and the pipeline of resin injection mouth.For example, preferably use resin injection flexible pipe, rubber tubulation etc. as filling line, and be inserted in bag material, be configured to join with the resin pervasion component.
Next, with bag material, cover such fibrage formed etc.In this forming process, bag material is normally used airtight plastic thin-film material preferably.And the encapsulants such as use adhesives connect airtight bag material fixing with respect to stacked body, and seal described fibrage etc.Thus, by airtight sealing between stacked body and bag material.
Next, liquid resin is injected in the inside to bag material under reduced pressure atmosphere.The liquid resin injected, owing to being in reduced pressure atmosphere, successfully is infiltrated up to described fibrage.As resin by injection, thermosetting resins such as the vinyl ester resin of preferred low viscosity system, unsaturated polyester resin, vinyl ester resin, epoxy resin, phenolic resins, isocyanate resin, bimaleimide resin, but can be also thermoplastic resin.By common method, above-mentioned resin being adjusted to proper viscosity uses.
Such resin injection reaches the reduced pressure atmosphere of regulation in bag material, and confirms not start after on the reinforcing fiber matrix material, there is no wrinkle.When resin by injection was used thermosetting liquid resin, heating and being shaped, in addition, while in resin by injection, adding curing agent, be shaped its sclerosis after adding curing agent.While using the liquid resin of thermoplasticity, after being heated to the resin injection of liquefaction, carry out coolingly, resin by injection is solidified.
Thus, had the thickness of wishing, and suppressed the generation of the wrinkle that caused by reinforcing fiber, can access the various formed products with good outward appearance and sufficient intensity.
The joint method of-cylinder element-
<embodiment 1 >
Next, with reference to accompanying drawing, the joint method of the cylinder element of embodiments of the present invention 1 is described.Fig. 1～Figure 11 is the figure of joint method of the cylinder element of explanation embodiment 1.In the present embodiment, as the example of cylinder element, the situation that engages two pitch tubes 10,10 is shown.In addition, in accompanying drawing shown below, in order easily to observe each member, emphasize thickness and schematically describe.
As shown in Figure 1, at first, the pitch tube 10,10 that engages object is docked to end surfaces (open end) each other and is configured.The end surfaces of pitch tube 10 is all cut off along the direction tilted.By the end surfaces by such, dock each other joint, pitch tube 10,10 is formed on the bend pipe of the shape of junction surface 101 part bendings.
As shown in Figure 2, under the state that the end surfaces that makes pitch tube 10,10 docks each other, in the mode across two pitch tubes 10,10, set reinforcing fiber matrix material 2 on its junction surface 101.In illustrative mode, reinforcing fiber matrix material 2 has along junction surface 101 outer peripheral face and the internal layer matrix material 21 that circumferentially is wound around and at the tabular outer matrix material 22 of overlapping multiple that set of the outside diameter of this internal layer matrix material 21.In state shown in Figure 2, in reinforcing fiber matrix material 2, at first, on junction surface 101, set internal layer matrix material 21.
Specifically, internal layer matrix material 21 is direct winfing base-materials (バ イ Application ダ mono-) on the outer peripheral face at junction surface 101.For example, internal layer matrix material 21 is the reinforcing fiber material to be formed to the form of glass chopped strand mats shape, and it is carried out to loop bonding processing and the material that obtains, preferably forms tabular matrix material.Like this, when internal layer matrix material 21 was the loop bonding matrix material of glass chopped strand mats, the power by the loop bonding line possessed shape retention, becomes the good material of servo-actuated property with respect to the outer peripheral face of pitch tube 10.
In addition, the outer matrix material 22 of reinforcing fiber matrix material 2 is for example that fibre bundle is drawn together, form rove, by the tabular fiber-based material that rove obtains for parallel forms fabric or nonwoven, wherein this fibre bundle obtains reinforcing fiber ultimate fibre boundling.
As previously mentioned, at first, along the outer peripheral face at the junction surface 101 of pitch tube 10, the internal layer matrix material 21 of the reinforcing fiber matrix material 2 of circumferentially reeling.Internal layer matrix material 21 is adapted to junction surface 101 and connects airtight.Make the width (with respect to the axial length that sets of pitch tube 10) of internal layer matrix material 21 form the size corresponding with junction surface 101, select stacked resin to engage needed width.
Next, as shown in Figure 3,4, at the periphery of the internal layer matrix material 21 of 101 the circumferential coiling along junction surface multiple tabular outer matrix materials 22 of overlapping overlap joint in turn.Outer matrix material 22 is plate objects of the rectangular shape of the size corresponding with the junction surface 101 of pitch tube 10,10.That is, outer matrix material 22 is equivalent to approximately by being cut into periphery length with respect to junction surface 101 that 1/16～1/2 length forms.
In illustrative mode, outer matrix material 22 is cut into outer perimeter by pitch tube 10 and is divided into the size that the length of six parts to two parts is suitable.The width of outer matrix material 22 is the width size about equally with internal layer matrix material 21.Especially, for the outer matrix material 22 of overlapping overlap joint on junction surface 101, and do not produce wrinkle, preferably the circumferential length of each outer matrix material 22 is formed on below 600mm.
Outer matrix material 22 set operation, by circumferential distolateral being adhesively fixed on internal layer matrix material 21 of an outer matrix material 22.In addition, not by the circumferential other end side bonds of this outer matrix material 22 on internal layer matrix material 21, but only overlapping with the outer surface of internal layer matrix material 21.
At this, for outer matrix material 22, with respect to the peripheral shape at the junction surface 101 that forms round-shaped or elliptical shape, the direction that makes to set an outer matrix material 22 is circumferential consistent with junction surface 101.At this, when outer matrix material 22 edges should circumferentially be configured, a circumferential end that the end (on one side) that sets a side of direction is called to outer matrix material 22, be called the end of opposite side (limit relative with aforementioned limit) other end of outer matrix material 22.
As shown in Figure 3, outer matrix material 22 is overlapping with the outer surface of the internal layer matrix material 21 of reeling before, and multiple outer matrix materials 22 are adapted to respectively along circumferentially reeling.Specifically, outer matrix material 22 of circumferential arrangement of 101 along junction surface, by a circumferential distolateral outer surface that is adhesively fixed on internal layer matrix material 21 of this skin matrix material 22.In addition, circumferential another of this skin matrix material 22 is distolateral not bonding, directly along the outer shape setting of pitch tube 10.The outer matrix material 22 then set too, circumferential one distolaterally with respect to internal layer matrix material 21, carry out bondingly it, and not bonding another is distolateral, make the outer surface of another another distolateral and adjacent outer matrix material 22 overlapped, repeatedly carry out this operation.
In addition, for reinforcing fiber matrix material 2 setting and fixing, to internal layer matrix material 21 and outer matrix material 22, can use and spray paste (blow pay け stick with paste) etc.
Like this, as shown in Figure 4, at multiple outer matrix materials 22 of the overlapping overlap joint of the outer surface of internal layer matrix material 21.By outer matrix material 22 along circumferentially every a certain amount of stacked above one another when its allocation position that staggers.Lap w with adjacent another outer matrix material 22 during stacked outer matrix material 22 guarantees to be the length more than 1/10 of length of an outer matrix material 22.In addition, in order to obtain the intensity based on outer matrix material 22, not being preferably formed outer matrix material 22 does not have lap, end to join each other or the allocation position of the state at interval each other.
By the above-mentioned operation that sets, as shown in Figure 5, can guarantee the stacked reinforcing fiber matrix material 2 in regulation wall thickness ground.
Next, and coiling flexible nonwoven fabrics 3 overlapping at the outer surface of above-mentioned stacked outer matrix material 22.As shown in Figure 6, flexible nonwoven fabrics 3 presses by multiple outer matrix materials 22 outer surface that is fixed on pitch tube 10.
In outer matrix material 22, although it is circumferential one distolateral only to be adhesively fixed, by this flexible nonwoven fabrics 3, pressed the structure of the stacked state of formation stable maintenance.In addition, because circumferential another of outer matrix material 22 is distolateral only overlapped with adjacent outer matrix material 22, therefore while by nonwoven 3, being involved in, can be under the state that does not produce unwanted wrinkle by outer matrix material 22 along junction surface 101 periphery fix.
Next, as shown in Figure 7, at the overlapping release cloth 4 that sets of the outer surface that is wound in the nonwoven 3 on junction surface 101.
And, if shown in Figure 8 and Figure 9, set resin diffusion part 5 at the outer surface of release cloth 4.
Next, as shown in Figures 10 and 11, at the both sides of the fibrolaminar width of reinforcing fiber matrix material 2 configuration relief line 8.In addition, at the outer surface of resin diffusion part 5, configure the ascending pipe 9 of resin by injection.Can make the size at junction surface 101 consistent with fibrolaminar size etc., ascending pipe 9 is set to many with appropriate intervals.
Next, at the outer peripheral face of pitch tube 10,10, cover above-mentioned reinforcing fiber matrix material 2 (fibrage), flexible nonwoven fabrics 3, release cloth 4, resin diffusion part 5, relief line 8, ascending pipe 9 (with reference to Figure 11) by bag film 6 air-tightness.At fibrolaminar circumference, use the encapsulants 7 such as adhesives or band bag film 6 to be bonded in to the outside of relief line 8.Thus, form the forming section of airtight sealing between pitch tube 10 and bag film 6.
When resin by injection, by the Reduced pressure source be connected with relief line 8, the inboard of suction bag film 6, form reduced pressure atmosphere.Now, confirm not produce wrinkle on stacked reinforcing fiber matrix material 2 (especially outer matrix material 22).Due to circumferential distolateral fixing respectively by the outer matrix material 22 of multiple overlapping overlap joint states only, do not fix circumferential another distolateral, therefore, even by bag film 6, seal and be depressurized and on outer matrix material 22, produce wrinkle, also can make wrinkle another non-bonding distolateral release to outer matrix material 22.Consequently, can effectively prevent the generation of the wrinkle of reinforcing fiber matrix material 2.In addition, now, also direct contact measurement confirm whether reinforcing fiber matrix material 2 forms the wall thickness of regulation.If by confirm as exist bad, can interruption operation, in the last stage of resin by injection, revise.
Under such reduced pressure atmosphere, from ascending pipe 9, supply with resin, make inboard (forming section in) diffusion of resin to bag film 6.The resin injected spreads all over integral body via resin diffusion part 5 and spreads equably, is infiltrated up to nonwoven 3 and reinforcing fiber matrix material 2.
When resin injection finishes, under the decompression state in maintaining bag film 6, make the resin by injection sclerosis.Thus, make reinforcing fiber matrix material 2 grades and resin by injection infiltration integrated.
When resin hardened fully, the joint at junction surface 101 finished.In addition, also can be in advance by stacked resins such as hands lay up method, the inner peripheral surface at junction surface 101 is carried out to inner surface treatment.
Thus, by the docking of the end surfaces of pitch tube 10,10, can easily engage.In addition, even have the bend pipe of such bend, also can engage.In addition, the reinforcing fiber matrix materials 2 in bag film 6 are not set with thering is no wrinkle, can form efficiently at short notice operation, and can form all good composite cylindrical bodies of the outward appearance of bonding part and intensity yet.Such joint method is not only applicable to straight tube or short tube, can both be suitable for any cylinder element, for example, as described later, goes for the junction blocks such as T junction or branched pipe etc. yet.
<embodiment 2 >
Next, with reference to accompanying drawing, the joint method of the cylinder element of embodiments of the present invention 2 is described.In addition, the joint method of the pitch tube 10 illustrated in present embodiment is identical with aforementioned embodiments 1 basic structure, because setting on mode of the outer matrix material 22 at reinforcing fiber matrix material 2 has feature, therefore, the mode that sets for this skin matrix material 22 is described in detail, for other structure, use the symbol shared with above-mentioned embodiment 1, and description thereof is omitted.
Figure 12 is the part sectioned view of an operation of joint method that the cylinder element of embodiment 2 is shown, and the section at the junction surface 101 of operation that will be corresponding with Fig. 3 amplifies and illustrates.
In the present embodiment, multiple tabular outer matrix materials 22 of the overlapping overlap joint of outer surface of the internal layer matrix material 21 set at 101 the outer peripheral face along junction surface, form sandwich construction, increased the wall thickness of outer matrix material 22, and formed uniform outer peripheral face.
In this situation, also the outer matrix material 22 that multiple are tabular along junction surface 101 circumferentially overlapping overlap joint in turn in the time of a certain amount of staggering.Now, circumferential distolateral being adhesively fixed on internal layer matrix material 21 of outer matrix material 22 by each, and by circumferential another distolateral with the not bonding this point of internal layer matrix material 21 on identical with embodiment 1.
As shown in figure 12, each outer matrix material 22 is overlapping with the outer surface of the internal layer matrix material 21 of reeling before, and multiple outer matrix materials 22 edges are circumferentially set respectively.Now, with the lap w of adjacent another outer matrix material 22, be set as larger than embodiment 1 outer matrix material 22.That is, make the outer matrix material 22 of an outer matrix material 22 with respect to adjacent other, few along the quantitative change of circumferentially staggering, guarantee that overlapped area is large.
At this, in the fibrage of the outer matrix material 22 that forms multilayer, the overlapped way of the circumferential end position consistency of the circumferential end position of not preferred outer matrix material 22 and other outer matrix material 22 of arbitrary layer.This is because the end of outer matrix material 22 may strength decreased in interlayer part consistent with each other.Therefore, as shown in figure 12, the other end F of a circumferential end E of arbitrary outer matrix material 22 and other arbitrary outer matrix material 22 is configured in along the position of circumferentially staggering.And, spread all over the complete cycle at junction surface 101 and guarantee outer matrix material 22 a certain amount of lap w each other.
Thus, easily stacked multiple outer matrix materials 22 guarantee wall thickness, in addition, can form the junction surface of uniform thickness.As subsequent processing, at the overlapping coiling flexible nonwoven fabrics 3 of the outer surface of so outer matrix material 22.
In addition, same with above-mentioned embodiment 1, configuration nonwoven 3 and release cloth 4 etc., and carry out the air-tightness covering by bag film 6.In the outer matrix material 22 of multiple overlapping overlap joint states, due to only distolateral fixing respectively by circumferential one, do not fix circumferential another distolateral, therefore, even seal and be depressurized by bag film 6, do not produce wrinkle yet, in Figure 12, wrinkle are discharged to the direction shown in arrow.Consequently, can effectively prevent the generation of wrinkle.In addition, now, also direct contact measurement confirm whether reinforcing fiber matrix material 2 forms the wall thickness of regulation.In addition, if having unfavorable condition by confirmation, can interruption operation, in the last stage of resin by injection, revise.
The manufacture method of-composite cylindrical body-
<embodiment 3 >
Next, with reference to accompanying drawing, the manufacture method of the composite cylindrical body of embodiments of the present invention 3 is described.In this manufacture method, manufacture the composite cylindrical body that has used a plurality of cylinder elements.
Figure 13 be from top view to the key diagram that cylinder element 10 is docked each other to situation about engaging, Figure 14 illustrates along junction surface 101 key diagrams that set the situation of multiple reinforcing fiber matrix materials 2.
For example, as shown in figure 13, open end is cut off or the part of outer peripheral face cut the section of cylinder element 10 dock each other.Then, as shown in figure 14, the outer peripheral face at the junction surface 101 after the docking of edge sets multiple reinforcing fiber matrix materials 2, forms fibrage (setting operation).
In this embodiment, be characterised in that the operation that sets of the shape of cylinder element 10 of cut-out and reinforcing fiber matrix material 2.That is, comprise in this manufacture method: with bag material, cover fibrage, and it is sealed in to the operation on the outer peripheral face of cylinder element 10; By the inner pressure relief of the bag material after sealing, to the inside of bag material, inject the operation of liquid resin; Make the liquid resin injected be infiltrated up to described fibrage, and make its sclerosis or curing operation, these operations are same as described above.Therefore, in the following description, omit the detailed explanation of above-mentioned each operation, mainly cylinder element 10 and reinforcing fiber matrix material 2 are described.
(distortion of cylinder element 10)
The cut-out mode of the open end of cylinder element 10 or the excision mode of outer peripheral face are varied, by by the aforesaid way combination, can manufacture various composite cylindrical bodies.That is the composite cylindrical body, obtained by this manufacture method is also in the category of technological thought of the present invention.
Illustration is as follows:
(1) will along inclined direction cut off two cylinder elements, 10,10 docking of open end, obtain the cylinder of curved shape.It can be with reference to the same operation of each operation with Fig. 1～shown in Figure 11.
(2) the first cylinder element is docked mutually with the second cylinder element, obtain the cylinder of T junction type, wherein, when the open end of this first cylinder element is cut off into from top view, be roughly V word shape or roughly U word shape, the part of the outer peripheral face of this second cylinder element is cut off into roughly V word shape or roughly U word shape accordingly with the section of the first cylinder element.This is example shown in Figure 13.
First cylinder element that (3) will along inclined direction cut off open end docks mutually with second and third cylinder element, obtain the cylinder of T junction type, when wherein the open end of this second and third cylinder element is cut off into from top view, be roughly V word shape or roughly U word shape.This is example shown in Figure 15.
(4) first and second cylinder element is docked mutually with the 3rd cylinder element, obtain the cylinder of T junction type, wherein the open end of this first and second cylinder element, by partial cutoff along inclined direction, is roughly V word shape or roughly U word shape when the open end of the 3rd cylinder element is cut off into from top view.This is example shown in Figure 16.
(mode that sets of reinforcing fiber matrix material 2)
In the manufacture method of composite cylindrical body of the present invention, reinforcing fiber matrix material 2 is plate objects of the size corresponding with junction surface 101, in setting operation, reinforcing fiber matrix material 2 is configured to local overlapped each other.Now, one side end of bonding reinforcing fiber matrix material 2, and make the outer surface of end side and adjacent reinforcing fiber matrix material 2 overlapping, make thus multiple reinforcing fiber matrix materials 2 along junction surface 101 overlapping overlap joints continuously, this is identical with illustrated mode in above-mentioned embodiment 1,2.The method that sets reinforcing fiber matrix material 2 can exemplify following various ways.
(5) along circumferentially staggering of junction surface, set the reinforcing fiber matrix material.This is example shown in Figure 17.
(6) along the width at junction surface and circumferentially stagger and set the reinforcing fiber matrix material.This is example shown in Figure 180.
(7) multiple reinforcing fiber matrix materials comprise sizes, set the reinforcing fiber matrix material along circumferentially staggering of junction surface.This is example shown in Figure 19.
(8) multiple reinforcing fiber matrix materials comprise the reinforcing fiber matrix material that width dimensions is different, set the reinforcing fiber matrix material along circumferentially staggering of junction surface.This is example shown in Figure 19.
In the manufacture method of the composite cylindrical body of embodiment 3, by suitable selection and combine distortion (1)～(4) of above-mentioned cylinder element 10 and the mode that sets (5)～(8) of reinforcing fiber matrix material 2, can manufacture the composite cylindrical body with this complicated shape of bend.At this, wherein several examples are described, but the present invention is not limited to following example.
(concrete example)
When as shown in figure 13, the open end of a cylinder element 10a is cut off into from top view, be roughly V word shape or roughly U word shape.The cut-out end face of the part of the outer peripheral face of another cylinder element 10b (central portion side) and cylinder element 10a is cut accordingly is roughly V word shape or roughly U word shape or round-shaped or elliptical shape while becoming from top view.
At first, cylinder element 10a, 10b are docked to section each other.Adhesive-applying, paste, sticker etc. on section, fix cylinder element 10a, 10b or temporarily fix and engage in advance.
Next, as shown in figure 14, at junction surface 101 and the cylinder outer surface of circumference one band set the reinforcing fiber matrix material 2 that is sheared into specific length.Now, as shown in figure 17, in order to form the thickness of regulation, reinforcing fiber matrix material 2, along circumferentially the staggering and set of junction surface, is carried out to overlapping overlap joint.
At this, around junction surface 101, for the end wall thickness of the width that makes reinforcing fiber matrix material 2 forms gently, can be as shown in figure 18, reinforcing fiber matrix material 2 also broad ways is mutually staggered and sets, or as shown in figure 19, reinforcing fiber matrix material 2 multiple overlapping overlap joints that width is different.By setting like this reinforcing fiber matrix material 2, because the stress of the end that can avoid width is concentrated, therefore preferably.
In addition, the C of the section of reporting to the leadship after accomplishing a task of the left and right reinforcing fiber matrix material 2 of Figure 14 compares with other parts, forms heavy wall.Because local heavy section infiltration speed when infiltrating resin is slow, therefore easily include the part of not infiltrating.For fear of this situation, by the reinforcing fiber matrix material 2 of the C of section of reporting to the leadship after accomplishing a task, using fiber is elongated to the reinforcing fiber matrix material at interval, can make wall thickness even, avoid the part of not infiltrating.
In addition, can be also after only the junction surface in the left side of Figure 14 101 is cascading into shape, stacked remaining right side, the method for carrying out identical shaping.
Specifically, for example, the diameter of cylinder element 10 is 500mm, and needing the number of reinforcing fiber matrix material 2 is 10, the length of one that makes reinforcing fiber matrix material 2 be junction surface 101 girth 1/4.In this case, the circumference of the section of cylinder element 10a
Figure BDA0000083628690000201
(being roughly 3.141 * (500+700)/2), the length of one of reinforcing fiber matrix material 2=1885/4
Figure BDA0000083628690000202
Lap (w)=472/10=47.2mm.That is, the length reinforcing fiber matrix material 2 that is 472mm the 47.2mm that staggers is laid equal stress on to be stacked with and connects, on the complete cycle at junction surface 101, put up 10 * 4=40 and open.
In example shown in Figure 14, when the width of first reinforcing fiber matrix material 2 is W, when length is L, make this W bonding stacked end face in ground that staggers a little.By doing like this, the reinforcing fiber matrix material 2 that can bondingly finally put up.And, with respect to junction surface 101, staggered each other in the position of reinforcing fiber matrix material 2 to come bonding end face as necklace, finally form a week, thereby as shown in the figure, cross initial stacked reinforcing fiber matrix material 2 and carry out overlapping overlap joint.Like this, the thickness at junction surface 101 all is being laminated with the thickness needed on intensity on any point.
Be described in further detail, Figure 17 is the schematic diagram at the junction surface 101 of the cylinder element 10 observed from above, is illustrated in 101De right side, junction surface half one by reinforcing fiber matrix material 2 ... 2 overlapping overlap joints and the form that sets.As previously mentioned, for initial reinforcing fiber matrix material 2 (width W, length L), when surpassing reinforcing fiber matrix material width W, carry out bonding to end face.Afterwards, along junction surface, 101 be the roughly bonding end face in windmill shape ground with certain spacing, stacked required number and form fibrage.Next, in half one of left side, be roughly windmill shape ground around counterclockwise overlapping overlap joint reinforcing fiber matrix material 2 ... 2, the reinforcing fiber matrix material 2 of required thickness on stacked intensity ... 2.
In addition, as shown in figure 18, the example of 101 width and the configuration reinforcing fiber matrix material 2 that circumferentially staggers along junction surface is described.For example, every 10mm, when staggering to the right in turn, 5 width of overlapping overlap joint are that 300mm, length are the reinforcing fiber matrix material 2 of 500mm.Next, overlapping overlap joint reinforcing fiber matrix material 2 when 10mm staggers left.And then when 10mm staggers, set reinforcing fiber matrix material 2 to the right, and set the thickness of regulation, form fibrage.So the fibrolaminar total width left and right formed by reinforcing fiber matrix material 2 is 400mm, in left and right end portions, produces the thin-walled portion of 50mm width extent, forms mild end.
Above set operation after, through with bag material, cover fibrage and by its be sealed in operation on described outer peripheral face, the inner pressure relief of bag material after seal and to the operation of the inside injection liquid resin of bag material, make the liquid resin injected be infiltrated up to described fibrage and make its sclerosis or curing operation, can access the composite cylindrical body 100 of union elbow type shown in Figure 20.
In addition, as shown in figure 15, in order to manufacture the composite cylindrical body 100 with same shape, the the first cylinder element 10c that along inclined direction cuts off open end mutually can be docked and engages with the second cylinder element 10d and the 3rd cylinder element 10e, when wherein, this second cylinder element 10d is cut off into from top view with the open end of the 3rd cylinder element 10e, be roughly V word shape or roughly U word shape.In this case, both can be by the disposable joint of whole cylinder elements, the cylinder element that also open end can be tilted to cut-out is engaged with each other, and the excision bend forms cylinder element 10d, 10e, finally cylinder element 10c docking is engaged.
In addition, as shown in figure 16, the first cylinder element 10f and the second cylinder element 10g are docked mutually with the 3rd cylinder element 10h, can access the cylinder 100 of T junction type, wherein, the open end of this first cylinder element 10f and the second cylinder element 10g, by partial cutoff along inclined direction, is roughly V word shape or roughly U word shape when the open end of the 3rd cylinder element 10h is cut off into from top view.
Thus, the section of cylinder element 10 is docked each other, even have the composite cylindrical body 100 of the complicated shape of bend, also can easily engage and form.In addition, the operation that sets by such reinforcing fiber matrix material 2, can avoid producing wrinkle in bag material (bag film 6), can form efficiently at short notice operation, can also form outward appearance and the good composite cylindrical body of intensity at junction surface 101.

With reference to accompanying drawing, the manufacturing process of the fiber-reinforced resin molded article of embodiments of the present invention 4 is described.Figure 21～Figure 26 illustrates the manufacturing process of the fiber-reinforced resin molded article of embodiment 4.
In the manufacturing process of the fiber-reinforced resin molded article of present embodiment, use the finishing die 1 with cylindrical portion.What finishing die 1 preferably be take cylinder axially is rotating shaft, is arranged to the rotational circle cylindrical shell that can rotate.In reinforcing fiber matrix material 2, use along the outer peripheral face of finishing die 1 along the internal layer matrix material 21 circumferentially set and the overlapping and stacked outer matrix material 22 in the outside of this internal layer matrix material 21.
At first, as shown in figure 21, set the internal layer matrix material 21 as base-material at the outer peripheral face of finishing die 1.Next, as shown in figure 22, when outer matrix material 22 was staggered in the overlapped mode in part, edge circumferentially set.The circumferential one distolateral of outer matrix material 22 is adhesively fixed.In addition, circumferential another of not bonding outer matrix material 22 is distolateral, is adapted to directly the outer shape along finishing die 1.It is bonding circumferential one distolateral that the outer matrix material 22 of next reeling similarly is adapted to, and not bonding another is distolateral, makes the distolateral overlapped of another another distolateral and adjacent outer matrix material 22.
As shown in figure 23, the lap w of during preferred stacked outer matrix material 22 and adjacent another outer matrix material 22, with respect to the circumferential lengths of an outer matrix material 22, guarantees the length more than 1/10.In addition, according to conditions such as the kind of reinforcing fiber matrix material and thickness, suitably select the stacked number of outer matrix material 22.The situation that stacked 10 left and right are for example arranged.In addition, the thickness of reinforcing fiber matrix material 2 can be selected at an easy rate according to the stacked number of outer matrix material 22, while setting an outer matrix material 22, reduce the amount of staggering with respect to the outer matrix material 22 of adjacent other, guarantee that overlapped area is large, thus, can form the stepped construction with thickness formed by multiple outer matrix materials 22.
In addition, under the state of stacked so outer matrix material 22, the overlapped way of the circumferential end position consistency of the circumferential end position of not preferred outer matrix material 22 and other outer matrix material 22 of arbitrary layer.At this, in this manufacturing process, the end of a circumferential end of arbitrary outer matrix material 22 and other arbitrary outer matrix material 22 is configured to form along the mode of the position of circumferentially staggering.And, spread all over the complete cycle of shaping mould 1 and guarantee outer matrix material 22 a certain amount of lap w each other, form fibrage.
As noted above, set and stacked outer matrix material 22 and, after forming the wall thickness of regulation, as shown in figure 24, be wound around flexible nonwoven fabrics 3.Circumferential one distolateral due to bonding outer matrix material 22 only, and another is distolateral only overlapped, therefore, when by nonwoven 3, being involved in, compression also can be to another distolateral release even stacked outer matrix material 2 is pressed, thereby can under the state that does not produce wrinkle, the periphery along finishing die 1 be fixed.
Next, as shown in figure 25, at the outer peripheral face winding release cloth 4 of the finishing die 1 that is wound with nonwoven 3.As shown in figure 26, the overlapping resin diffusion part 5 that sets in the outside of release cloth 4.In the outside of resin diffusion part 5, configure the ascending pipe 9 of resin by injection.The configuration mode of ascending pipe 9 is random, but near preferably being arranged at the bottom of the pipe of finishing die 1.And, set not shown relief line, around 6 coverings of use bag film are fibrolaminar.Next, by Reduced pressure source, by the interior decompression of bag film 6, inject liquid resin.Now, confirm there is no wrinkle on stacked reinforcing fiber matrix material (outer matrix material 22) etc.Direct contact measurement be confirmed whether to form the wall thickness of regulation.In addition, by above-mentioned confirmation, if the unfavorable condition of existence, can interruption operation, revise.Resin by injection spreads equably, infiltrates to whole fibrage via resin diffusion part 5.
When resin injection finishes, under the decompression state in maintaining bag film 6, make resin by injection sclerosis, make itself and reinforcing fiber matrix material 2 integrated.Next, from finishing die 1 demoulding, the edge of finishing formed body cylindraceous, can access fiber-reinforced resin molded article by the formed body after solidifying.
The manufacturing process of the fiber-reinforced resin molded article by above structure does not set the reinforcing fiber matrix material 2 in bag film 6 with can thering is no wrinkle, can form efficiently at short notice operation, can form all good formed products of outward appearance and intensity.
<embodiment 5 >
Next, with reference to accompanying drawing, the manufacturing process of the fiber-reinforced resin molded article of embodiments of the present invention 5 is described.Figure 27～Figure 33 illustrates the manufacturing process of the fiber-reinforced resin molded article of embodiment 5.
In illustrative mode, as Figure 27 and shown in Figure 28, use the finishing die 1 with forming face corresponding with half point cyclotomy tubular.Utilize the shown in Figure 27 shape mould 1 that partly is divided into, can access the fiber-reinforced resin molded article of T junction type.In addition, utilize the shown in Figure 28 shape mould 1 that partly is divided into, can access the fiber-reinforced resin molded article of union elbow type.In such finishing die 1, the inner peripheral surface that both fibre strengthening matrix material 2 can be provided in to finishing die 1 forms, and the outer peripheral face that also can be provided in finishing die 1 forms.
The reinforcing fiber matrix material 2 set comprises internal layer matrix material 21 and outer matrix material 22.At first, along the side face that partly is divided into shape mould 1, set internal layer matrix material 21.Reinforcing fiber matrix material 2 set operation, along inner peripheral surface, set outer matrix material 22, and make it along circumferentially staggering.
As shown in figure 29, when the inner peripheral surface by partly being divided into shape mould 1 forms, form fibrage by reinforcing fiber matrix material 2, and, as shown in figure 30, suitably set nonwoven 3, release cloth 4, resin diffusion part etc., and cover with bag film 6.In bag film 6, also be equipped with relief line and ascending pipe 9 etc.Thus, can access half point and cut fiber-reinforced resin molded article cylindraceous, a pair of formed body is engaged with each other, form the formed products of T junction type or union elbow type.
In addition, as shown in figure 31, when the outer peripheral face by partly being divided into shape mould 1 forms, along circumferentially setting respectively multiple outer matrix materials 22, reel with overlapping with the outer surface of the internal layer matrix material 21 of reeling before.Specifically, along partly being divided into the outer peripheral face of shape mould 1, along circumferentially settling an outer matrix material 22, by the circumferential one distolateral outer surface that is adhesively fixed on internal layer matrix material 21 of this skin matrix material 22.In addition, not bonding circumferential another that should skin matrix material 22 is distolateral, directly along the outer shape that partly is divided into shape mould 1, arranges.Next the outer matrix material 22 set similarly be adapted to by its circumferential one distolateral with respect to internal layer matrix material 21, carry out bonding, and, another is distolateral not overlapped with the outer surface of adjacent another outer matrix material 22 adhesively.Reinforcing fiber matrix material 2 set and fixing in, on internal layer matrix material 21 and on outer matrix material 22, can use and spray paste etc.
In above-mentioned example, according to the external diameter that partly is divided into shape mould 1, outer matrix material 22 is formed to the plate object that is cut into specific length.In illustrative mode, outer matrix material 22 is cut apart to the suitable size of six length of cutting apart and is formed rectangle with the outer perimeter two with partly being divided into shape mould 1, and by it along circumferential overlapping overlap joint.Circumferential distolateral being adhesively fixed on internal layer matrix material 21 of the outer matrix material 22 of each of overlapping overlap joint, circumferential another is distolateral not to be arranged on internal layer matrix material 21 adhesively.
Next, shown in figure 32, at the outer surface coiling flexible nonwoven fabrics 3 of outer matrix material 22, be fixed in the mode that does not produce unwanted wrinkle on outer matrix material 22.In addition, as shown in figure 33, also outer matrix material 22 can be formed to multilayer.In the fibrage of outer matrix material 22, the consistent overlapped way of circumferential end position of the outer matrix material 22 that circumferential end position and other of not preferred outer matrix material 22 is arbitrary layer, can be configured the other end F of a circumferential end E of arbitrary outer matrix material 22 and other arbitrary outer matrix material 22 to form along the mode of the position of circumferentially staggering.And, spread all over the whole outer peripheral face that partly is divided into shape mould 1 and guarantee outer matrix material 22 a certain amount of lap w each other.
Overlapping and set release cloth 4 at the outer surface of nonwoven 3, and cover with bag film 6.Then, at the circumference that partly is divided into shape mould 1, use the encapsulants such as adhesives or band bag film 6 to be fixed on to the surface that partly is divided into shape mould 1.
Thus, can make partly to be divided into the forming section that forms airtight sealing between shape mould 1 and bag film 6.In addition, on the forming section covered by bag film 6, be connected with the air in suction mold section and the Reduced pressure source that reduces pressure.
Next, by the decompression of the inboard of bag film 6, under the state that forms the substantial vacuum state, liquid resin infiltrates by Reduced pressure source.Now, confirm not produce wrinkle on the reinforcing fiber matrix material 2 (especially outer matrix material 22) after stacked.Due to circumferential distolateral fixing respectively by the outer matrix material 22 of the state of multiple overlapping overlap joints only, and it is distolateral not fix circumferential another, therefore, even seal and be depressurized and on outer matrix material 22, produce wrinkle by bag film 6, also can make wrinkle another non-bonding distolateral release to outer matrix material 22, consequently, can effectively prevent the generation of wrinkle.In addition, now, direct contact measurement confirm whether reinforcing fiber matrix material 2 forms the wall thickness of regulation.In addition, by confirming, if the unfavorable condition of existence, can interruption operation, in the last stage of resin by injection, revise.
When resin injection finishes, resin by injection is solidified, thus, make resin by injection and the infiltration of reinforcing fiber matrix material integrated, obtain partly cutting apart the formed products of shape.And, by combining one, divide half-and-half the formed products that cuts shape and engage, can form the formed products of union elbow type or T junction type.
<embodiment 6 >
Next, with reference to accompanying drawing, the manufacturing process of the fiber-reinforced resin molded article of embodiments of the present invention 6 is described.Figure 34～Figure 37 illustrates the manufacturing process of the fiber-reinforced resin molded article of embodiment 6.Figure 34 is the stereogram that an example of finishing die is shown, Figure 35 (a)～Figure 35 (d) is the top view that the example of reinforcing fiber matrix material is shown respectively, Figure 36 is an operation of this manufacturing process, is the stereogram that is illustrated schematically in the situation of overlapping overlap joint matrix material on finishing die.In addition, Figure 37 is the profile that is illustrated schematically in the state before resin injection in this manufacturing process.
In the manufacturing process of the fiber-reinforced resin molded article of present embodiment, replace the finishing die 1 formed by the such cylinder of embodiment 5, as shown in figure 34, the finishing die 1a that use has cylindrical portion 11 and flange part 12 carrys out the forming belt flanged pipe.That is, the finishing die 1a flange part 12 that has the end periphery of cylindrical portion 11 and cylindrical portion 11 as the forming face corresponding with the flanged pin pipe.
Reinforcing fiber matrix material 2 is used the matrix material 23 of strip plate shape, and wherein this matrix material 23 has the part set on the cylindrical portion 11 of finishing die 1a and the part set on flange part 12 integratedly.That is, matrix material 23 has across the cylindrical portion 11 of finishing die 1a and flange part 12 both sides' a shape, can be illustrative variety of way in Figure 35 (a)～Figure 35 (d).
Specifically, the matrix material 23 of above-mentioned strip has corresponding with the profile of finishing die 1a respectively shape.For example in the matrix material 23 shown in Figure 35 (a), the upper portion 231 of matrix material 23 is larger than lower quadrate part 232, and forms rectangular shape, sets along the outer peripheral face of the cylindrical portion 11 of finishing die 1a.In addition, lower quadrate part 232 is less than upper portion 231, sets along the outer peripheral face (upper surface) of the flange part 12 of finishing die 1a.The cylindrical portion 11 of the size of a matrix material 23 and finishing die 1a and the size of flange part 12 are corresponding and form, and with the completing consistent size of formed products, suitably select finishing die 1a.In this case, when the width of the matrix material 23 of a strip with respect to finishing die 1a too hour, overlapping overlapping number increases, workload is also increased, thus not preferred, in addition, when width is too large, overlap that the effect of eliminating wrinkle when overlapping dies down and not preferred.Therefore, the width of preferred substrate material 23 is the outer perimeter with respect to cylindrical portion 11, the width suitable with 1/16～1/2 length.
In addition, as shown in Figure 35 (b), the lower quadrate part 232 of matrix material can form the wide trapezoidal shape in bottom.Also can be as shown in Figure 35 (c) and Figure 35 (d), it is wide that whole matrix material 23 forms bottom, and as shown in Figure 35 (c), whole matrix material 23 has trapezoidal shape, or as shown in Figure 35 (d), whole matrix material 23 has down fan shape.
When the flanged pin pipe is shaped, reinforcing fiber matrix material 2 set operation, along the outer peripheral face of finishing die 1a, along circumferentially overlapping in turn overlapping multiple matrix materials 23 with above-mentioned shape.For each matrix material 23, outer peripheral face along cylindrical portion 11 sets upper portion 231, upper surface along flange part 12 sets lower quadrate part 232, and, with the mode of the recessed corner part along between cylindrical portion 11 and flange part 12 the bend inwards upper portion 231 of configuration matrix material 23 and the border 23a of lower quadrate part 232.
In addition, same with above-mentioned embodiment, as base-material, can internal layer matrix material 21 be provided on the cylindrical portion 11 of finishing die 1a in advance.
Next, the adjacent matrix material set 23 set and carries out overlapping overlap joint in the mode circumferentially misplaced respectively along finishing die 1a, reeling thus.Specifically, as shown in figure 36, circumferential distolateral (long leg) 233 of matrix material 23 is adhesively fixed on the outer peripheral face (or internal layer matrix material 21) of finishing die 1a.In not bonding mode, directly along the outer shape of finishing die 1a, set circumferential another of matrix material 23 distolateral.Next it is bonding circumferential one distolateral that the matrix material 23 set is adapted to similarly, and by another distolateral distolateral overlapped with not bonding mode and adjacent another matrix material 23.
Next, multiple matrix materials 23 are overlapping with respect to the cylindrical portion 11 of finishing die 1a and flange part 12 overlap joints, and in the mode that does not produce wrinkle, connect airtight stacked, to guarantee the thickness that obtains stipulating.That is, only one of matrix material 23 distolateral side edge part 233 use pastes are pasted in turn, every necessary length along circumferential misalignment, thereby on finishing die 1a the overlapping matrix material 23 of overlap joint and carry out multilayer laminated.
As shown in figure 36, during stacked matrix material 23, preferred substrate material 23 and the lap of adjacent another matrix material 23 guarantee to be the length more than 1/10 of circumferential lengths of a matrix material 23.In addition, according to conditions such as the kind of reinforcing fiber matrix material 2 and thickness, suitably select the stacked number of matrix material 23.
In illustrative mode, the thickness of reinforcing fiber matrix material 2 can be selected at an easy rate according to the stacked number of the overlapping matrix material 23 of overlap joint.In addition, while setting a matrix material 23, reduce the amount of staggering with respect to another adjacent matrix material 23, large to guarantee overlapped area, thus, can form the stepped construction with thickness formed by multiple matrix materials 23.
Now, under the state of stacked matrix material 23, the circumferential end position of preferred substrate material 23 overlapped way consistent with the circumferential end position of other the matrix material of arbitrary layer 23 not, the other end of the circumferential end position of preferred arbitrary layer of matrix material 23 and the matrix material 23 of other layer forms along the position of circumferentially staggering.
When stacked complete matrix material 23 on finishing die 1a, next, the nonwoven 3 of reeling and having retractility, press matrix material 23 to remain on finishing die 1a above, and be fixed (with reference to Figure 37).For multiple stacked matrix materials 23, due to only bonding circumferential one distolateral, another is distolateral only overlapped, therefore, when coiling nonwoven 3, even matrix material 23 is pressed and is oppressed, also can make this active force to another distolateral release, thereby can not produce wrinkle ground, be fixed on each matrix material 23 along the outer peripheral face of finishing die 1a.
And, in the mode be wound around, configure release cloth 4 on the outer peripheral face of the finishing die 1a that is wound with nonwoven 3.As shown in figure 37, preferably with the reinforcing fiber matrix material 2 of cover layer poststack and the mode of nonwoven 3 integral body, set release cloth 4.
Next, at the outside of release cloth 4 configuration resin diffusion part 5.As shown in figure 37, the scope of configuration resin diffusion part 5 is the end of the reinforcing fiber matrix material 2 on from the Shao Dide position, upper end of the reinforcing fiber matrix material 2 than after stacked to flange part 12.In addition, according to the stacked thickness of reinforcing fiber matrix material 2 and the conditions such as kind of material, when not affecting formability, also can omit resin diffusion part 5.
In the top of finishing die 1a, the inboard of release cloth 4, set relief line 81.Relief line 81 connects the Reduced pressure source such as vavuum pump via flexible pipe 8.In addition, the ascending pipe of resin by injection 9 is set with respect to reinforcing fiber matrix material 2 stacked on the flange part 12 at finishing die 1a.The mode that sets of ascending pipe 9 is random, but preferably is arranged near the flange part 12 of finishing die 1a.
Next, by bag film 6 air-tightness, cover the finishing die 1 that has set above-mentioned release cloth 4 and resin diffusion part 5 and ascending pipe 9 etc.In addition, set the encapsulants 7 such as adhesives or band in the upper periphery of the cylindrical portion 11 of finishing die 1a and the circumference of flange part 12, bag film 6 is fixed in to the surface of finishing die 1a and seals.Thus, make between finishing die 1a and bag film 6 to form forming section airtight and sealing.
When resin by injection, by Reduced pressure source, reduced pressure in the inboard of bag film 6.Now, confirm not produce wrinkle on stacked matrix material 23 grades.Also can be from direct contact measurement be confirmed whether to form the thickness of regulation on bag film 6.In addition, by above-mentioned confirmation, if the unfavorable condition of existence, can interruption operation, revise.
Next, under reduced pressure atmosphere, from ascending pipe 9 resin by injections, and resin is spread in forming section.Resin by injection spreads all over integrally evenly diffusion via resin diffusion part 5, is infiltrated up in nonwoven 3 and reinforcing fiber matrix material 2.When using thermal sclerosing material as resin by injection, by heating or in resin, add curing agent and make its sclerosis, can access the formed products of regulation shape.When using thermoplastic resin, be heated to liquefaction, after resin by injection, remaining under decompression state, that whole finishing die 1a is cooling and curing, make resin by injection and the infiltration of reinforcing fiber matrix material integrated.From after the finishing die 1a demoulding, finishing forms the edge of cylindric and flange shape formed body, can access the formed products of flanged pin pipe by the formed body that solidified.
As mentioned above, manufacturing process by fiber-reinforced resin molded article of the present invention, can set the reinforcing fiber matrix material 2 (23) in bag film 6 non-wrinklely, can form efficiently at short notice operation, and outward appearance that can the forming shaped product and intensity good formed products all.
<embodiment 7 >
Next, with reference to accompanying drawing, the manufacturing process of the fiber-reinforced resin molded article of embodiments of the present invention 7 and the joint method of cylinder element are described.Figure 38～Figure 43 is the figure of explanation embodiment 7, Figure 38 is the stereogram that the formed products obtained in embodiment 7 is shown, Figure 39 is the top view of an example that the reinforcing fiber matrix material (matrix material) of use is shown, Figure 40 is the profile of state that the matrix material of stacked Figure 39 is shown, Figure 41 is the stereogram that an example of finishing die is shown, and Figure 42 is the key diagram that schematically shows a forming process using finishing die shown in Figure 41.In addition, Figure 43 is by the key diagram of the operation after the Figure 42 shown in section.
In this embodiment 7, as shown in figure 38, form the formed products 100 of the shape that possesses integratedly flange 102 and cylinder (10s, 10t).When being shaped, formed products 100 is used to the manufacturing process in two stages.That is, at first, the manufacturing process of the fiber-reinforced resin molded article by present embodiment is shaped the first formed products 10r, and this first formed products 10r obtains by integrally formed cylindrical portion and flange part.Next, the joint method of the cylinder element by present embodiment engages the first formed products 10r and main body tube 10s integrated.Thus, form formed products 100 shown in Figure 38.
The first formed products 10r becomes the formed products of the flange 102 of main composition formed products 100, when the first formed products 10r is shaped, uses the finishing die 1a with embodiment 4 same way as with cylindrical portion 11 and flange part 12.
As shown in figure 39, consider the size of the flange 102 of the first formed products 10r and formed products 100, the reinforcing fiber matrix material 2 that will set on finishing die 1a in advance forms roughly discoid.For example, as shown in figure 39, can use the tabular matrix material 24 of the appearance and size circle corresponding with the size of flange 102, central portion is cut into to circle, form through hole 241.
And, around the through hole 241 of matrix material 24, be many otch of radial formation, thereby form a plurality of sheets 242 that erect.Thus, in matrix material 24, when in through hole 241, inserting the cylindrical portion 11 of logical finishing die 1a, the above-mentioned sheet 242 that erects erects along the outer peripheral face of cylindrical portion 11.Thereby, the external diameter of through hole 241 and the size that erects sheet 242 and the cylindrical portion 11 of finishing die 1a is corresponding and form.
The matrix material 24 of shape is before being configured on finishing die 1a like this, can be in advance stacked multiple and prepare.As shown in figure 40, make the position consistency of through hole 241 and stacked multiple matrix materials 24.Preferably by each matrix material 24 to erect sheet 242 stacked in advance, in order to avoid with other matrix material 24 location overlaps.That is, when stacked multiple matrix materials 24, that matrix material 24 is a certain amount of along rotating in a circumferential direction, when with respect to stacked below matrix material 24 edges, circumferentially staggering, carry out stacked.Thus, when erecting sheet 242 and erect, can form uniform stacked state, effectively guarantee the intensity of formed products 10r.
As shown in figure 40, if stacked matrix material 24, by under above-mentioned matrix material 24 shape all-in-one-piece states, is embedded in the cylindrical portion 11 of finishing die 1a shown in Figure 41.The sheet 242 that erects of stacked matrix material 24 erects respectively in cut out portion, becomes the part (with reference to Figure 42) set along the outer surface of the cylindrical portion 11 of finishing die 1a.Consider the embedding workability of matrix material 24, the cylindrical portion of finishing die 1a 11 can be formed to conical shaped shape or truncated cone shape.
Next, as shown in figure 42, set bag film 6 at the outer peripheral face of finishing die 1a, thereby air-tightness covers reinforcing fiber matrix material 2 (matrix materials 24 after stacked).In addition, set the encapsulants 7 such as adhesives or band in the upper periphery of the cylindrical portion 11 of finishing die 1a and the circumference of flange part 12, bag film 6 is fixed on to the surface of finishing die 1a and seals.Thus, forming section airtight and sealing will be formed between finishing die 1a and bag film 6.
In addition, on the top of finishing die 1a, set not shown decompression pump orifice and relief line, connect Reduced pressure source.And, with respect to reinforcing fiber matrix material 2 stacked on the flange part 12 at finishing die 1a, set the ascending pipe of resin by injection.
When resin by injection, by Reduced pressure source, reduced pressure in the inboard of bag film 6.Now, confirm not produce wrinkle on stacked matrix material 24.Also can be from direct contact measurement be confirmed whether to form the wall thickness of regulation on bag film 6.In addition, by above-mentioned confirmation, if the unfavorable condition of existence, can interruption operation, revise.
Next, under the reduced pressure atmosphere formed by vacuum draw, from ascending pipe, inject liquid resin, and it is spread in forming section.Resin, via resin diffusion part 5, spreads all over all diffusion equably, to nonwoven 3 and 2 infiltrations of reinforcing fiber matrix material.
The formed body that solidified from after the finishing die 1a demoulding, is formed to the edge of cylindric and flange shape formed body by finishing, obtain the first formed products 10r.
Next, as shown in figure 43, with respect to the finishing die 1b with cylindrical portion 11 and flange part 12, embed the first formed products 10r from cylindrical portion 11, be placed on the flange part 12 of finishing die 1b.Internal diameter and the roughly the same main body tube 10s of profile are embedded and are positioned on the upper end of the first formed products 10r from the cylindrical portion 11 of finishing die 1b.Thus, the upper surface of the first formed products 10r is docked with the lower surface of main body tube 10s, carry out mutual butt.
So, under the state that makes the first formed products 10r and the mutual butt of main body tube 10s, be placed in finishing die 1b upper after, the upper surface that makes the first formed products 10r engages with the lower surface of main body tube 10s and integrated.At this, in the joint method of present embodiment, set reinforcing fiber matrix material 2 (setting operation) in the mode of both ends of the surface across docking.Thus, become the formed products 10t at junction surface.
For reinforcing fiber matrix material 2 can use with above-mentioned embodiment in the same matrix material of the outer matrix material 22 that illustrates.103 periphery is wound around internal layer matrix material 25 along junction surface, next, implements the operation that sets of multiple outer matrix materials 26 overlapping overlap joint along circumferentially reeling in turn.
According to the external diameter at the junction surface 103 of the first formed products 10r and main body tube 10s, outer matrix material 26 is cut into to the length of regulation, form rectangular shape.
By circumferential distolateral being adhesively fixed on internal layer matrix material 25 of outer matrix material 26, be not arranged on adhesively on internal layer matrix material 25 circumferential another is distolateral.The method for winding of outer matrix material 26 is preferably overlapping with the outer surface of the internal layer matrix material 25 of reeling before, and by multiple outer matrix materials 26 circumferential said methods that set respectively in edge.
